Burton: Lincolnshire Coast Boulders. 327 
prior to 1586—the date of Camden’s work—and he says, ‘There 
is only one possible answer: it is distributed along the coast 
south of the Humber.’ This is entirely begging the question, 
for it assumes that the material, from whatever source it comes, 
once on the south side of the river, would be able to reach the 
coast and be carried down it by currents; a fact which, after 
reading Mr. Wheeler’s lucid account of wave and tidal action 
generally, and of that of the district in question in particular, 
seems to me impossible. 
On the other hand, I would ask what has become of all the 
material which has been denuded from the boulder cliffs of the 
Lincolnshire coast? And, again, which is the most likely to be 
the case, that the material now found there should have been 
derived from the northern side of the Humber current, whic 
would prevent its crossing to the south; or, from the southern 
Lincolnshire side, where it would have no current to oppose it, 
and where the material lies ready to hand ? 
In connection with the question of currents, Mr. Harker in 
Lincolnshire oni we ee no element of 
that kind; ait - sand and mud; and the boulders, which lie 
hidden under it, are only occasionally revealed when storms 
have swept the covering of sand and mud from off them. With 
reference to this latter coast Mr. Wheeler says :—‘On this 
beach there is no appreciable littoral drift or alteration in form. 
Sand does not accumulate against the piers or groynes which 
extend across the shore; and the general outline of the beach 
remains as it always has been so far as any record exists.’ 
That this is so, surely the large bank of shingle at Donna Nook 
is a proof, for if any strong drift existed would not this bank be 
carried down the shore instead of eenee heaped up as 
Mr. Clement Reid describes it ? 
The whole of the evidence, as well as the facts, seem to m 
to point conclusively to the erratics on the Lincolnshire ac 
November 1899.
